AI electrical estimating software reads a set of electrical drawings and produces the quantities and labor hours behind a bid, along with the price. On the drawings, that means the equipment on the single-line diagram, the fixtures and devices on the plans, the cable on the cable schedule and the instruments on the instrument index.
By hand, an estimator counts each symbol sheet by sheet, traces every conduit and cable run with a scale or an on-screen measuring tool, and types the quantities into a spreadsheet. The labor hours and the pricing only start once that count is finished.
That way of working no longer holds, because electrical contractors have fewer estimators carrying more bids, and the packages keep getting bigger. A week spent counting one job is a week the next two bids wait.
Below is how The Takeoff AI does electrical estimation, step by step, ending with a priced bill of materials (BOM) you can check against the drawings.
What The Takeoff AI Estimates From
The Takeoff AI estimates from your electrical and instrumentation (E&I) drawings. That includes single-line diagrams, lighting and device plans, panel schedules, cable schedules and the instrument index. It is built on AI models trained on more than 1.2 million electrical and instrumentation drawings, so it recognizes the symbols and schedules estimators see on commercial and industrial jobs.

How The Takeoff AI Does Electrical Estimation in 6 Steps
1. It Reads the Full Drawing Set
The Takeoff AI reads every sheet in the electrical package together, including the schedules. A panel on the single-line diagram is matched to its panel schedule, and a cable on the cable schedule is matched to its route on the plan.
2. It Counts Every Device and Piece of Equipment
The Takeoff AI counts the equipment and devices by type. From the single-line diagram it counts feeders, breakers, transformers, motor control center (MCC) buckets and motor loads. From the lighting and device plans it counts receptacles, switches, light fixtures and junction boxes. Instruments are counted by tag.
3. It Measures Conduit, Cable and Cable Tray
The Takeoff AI measures cable, tray and conduit lengths along the route. When the cable schedule gives no length, it takes the length from the scaled plan and flags that line as measured. It also splits the cable footage between tray and conduit, which matters because the two install at different labor rates.
4. It Adds the Materials the Drawings Don't Show
The Takeoff AI adds the derived materials that never appear as symbols. Seals, glands, fittings and supports are worked out from the specification and the area classification, so a hazardous area gets the sealing fittings it needs.
5. It Builds the Labor Takeoff and Prices the Job
The Takeoff AI puts labor hours and a price on every line. The labor starts from labor units published by the National Electrical Contractors Association (NECA) or from your own productivity rates. The pricing covers material and labor, and the result is a priced BOM.
6. It Highlights Every Number on the Drawing
The Takeoff AI delivers 95% accuracy, and every number is marked and highlighted on the drawing it came from, so someone can check it before the bid goes out. Click a count of 214 receptacles and the 214 symbols are highlighted across the sheets.

What You Get at the End
You get three outputs: the material takeoff (MTO), the labor takeoff and a priced BOM. The Takeoff AI also builds a 3D model from the 2D electrical drawings, so the estimator can walk the cable tray and conduit routes and catch a clash before the bid.
How Long Electrical Estimation Takes on The Takeoff AI
Electrical estimation on The Takeoff AI takes 2 to 3 hours for projects that used to take 30 to 40 hours. That saves estimators 90 to 95% of their estimating time, and the hours go back into reviewing scope and chasing the next bid. More than 157 electrical estimators say The Takeoff AI saves them 90% of their estimating time.
How The Takeoff AI Compares With Other Electrical Estimating Software
We compared 10 electrical estimating software tools side by side, and you can read the full comparison in 10 Best AI Electrical Estimating Software in 2026.
The Takeoff AI is the best AI electrical estimating software for contractors who need the takeoff done and priced in hours. It counts and measures from the drawings where other tools leave the clicking to the estimator or stop at symbol counts. It prices the takeoff into a priced BOM, and every number is highlighted on the drawing it came from, so the estimator checks the work before bidding.
Why Electrical Contractors Are Moving Off Manual Estimating
Electrical contractors are moving off manual estimating because there are fewer estimators to do the counting. The Bureau of Labor Statistics (BLS) counts about 221,400 cost estimators in the US and projects a 4% decline by 2034, and roughly three in four estimator seats will need to be refilled over the decade. The Shortage of Estimators report has the full picture.
The bid load keeps growing at the same time, and data centers are a large part of it. The Data Center Boom Has A Problem covers what that means for contractors, and The Takeoff AI suits electrical firms expanding into data centers.

FAQs
How Accurate Is AI Electrical Estimating Software?
The Takeoff AI delivers 95% accuracy on electrical takeoffs. Every number is highlighted on the drawing it came from, so an estimator can check it and correct it before the bid goes out.
How Much Time Does AI Save on an Electrical Estimate?
Estimators using The Takeoff AI finish projects in 2 to 3 hours that used to take 30 to 40 hours. That is 90 to 95% of their estimating time saved.
Does The Takeoff AI Do Electrical and Instrumentation (E&I) Estimating?
Yes. The Takeoff AI estimates from both electrical drawings and the instrument index, and it counts instruments by tag alongside the cable, conduit and tray.
How Do I Check an AI Electrical Takeoff Before I Bid?
Click any line on the takeoff and The Takeoff AI shows where that count or length came from on the sheet. Start with the largest lines, such as feeders and cable tray, and confirm them against the drawing.
Are My Drawings Secure on The Takeoff AI?
The Takeoff AI is SOC 2 Type II compliant. Each customer company gets its own dedicated tenant.
Conclusion
There are fewer electrical estimators every year, and counting symbols and measuring cable by hand takes the most of their time. The Takeoff AI is the best AI electrical estimating software for contractors who need the takeoff done and priced in hours.
